다국어 초록 (Multilingual Abstract)

The period of 4th century BC is when the culture was transferred from mandolin-shaped bronze dagger culture to the slender bronze dagger culture. In Gojoseon in this period, Joseonhu called himself as a king and made a lot of fights severe enough to think of the possible fight with Yan to get the hegemony in the region. In addition, according to the theory on movement of central place of Gojoseon, this period was when Gojoseon assumed Liaodong as its central place and integrated with the surrounding regions to make a big growth. As such, it is highly likely that the change in the materialistic cultures in Liaoxi area happened in 4th century BC on the background of the history specified above. Particularly, it was found out from Dongdazhangzi Cultural Assemblage which represented the materialistic culture in Liaoxi Region in 4th century BC that the mandolin shipped dagger culture was transferred over to the slender bronze dagger culture and that the culture of Yan in Warring States Period was spread around the area and the active cultural exchange with Yan was made in the area. On the other hand, the cultural change in Liaoxi Region in 4th century BC contributed to the ramification of Slender Bronze Daggers Culture in the Liaoning Area and the western area of Korean peninsula. The materialistic culture in Gojoseon in 3rd century BC is considered to have had the close relationship with the cultural change in Liaoxi as the cultures of Tombs with wooden coffin filled stones, bronze weapons and pottery of Dongdazhangzi Cultural Assemblage were transferred along with Zhengjiawazi Cultural Assemblage to the culture of Slender Bronze Daggers Culture in area of Liaodong and western and northern Korean peninsula. The prior documents show that in late period of Gojoseon, Gojoseon internally grew along with the surrounding groups by either dominating them or subduing them and externally competing with Yan and making exchanges with them to a certain level. It is clearly found in Dongdazhangzi Cultural Assemblage that there were highly advanced tomb system in Liaoning in 4th century BC and that they were transferred to the Slender Bronze Daggers Culture in 3th century BC as well as that there were bronze weapons and pottery and the cultural exchanges with Yan. It is expected that the relation between Dongdazhangzi Cultural Assemblage and Slender Bronze Daggers Culture is a good clue for the understanding of the relation between Gojoseon and surrounding groups in late period of Gojoseon.
